NoN-sKIDDmG DEVICE For. WHEELS-or meedeed sept. 22, 190s To "all whom.it may concern.'

Be it known that I, Hnxnv HARDING KENsnoLn, engineer, a subject of theKing of Great Britain, residing at The Ehns, Goodmaycs, Ilford, in thecounty of Essex, England, have invented a certain new and usefulImproved Non-Skidding Device for Wheels of Vehicles, of which thefollowing is a specication. v

My invention relates to an improved device for automatically preventingthe skidding or side slipping of the wheels ofl road p vehicles.

According to my invention I mount an eccentric sheave or bearing bossupon the axle ne ar to the wheel or between two parts of a wheel, meansbeing provided whereby when lateral or axial motion is applied theeccentric boss is more or less rotated to bring its eccentricity towardsthe road. Upon this boss is rotatably mounted a disk or dummy wheelformed with a serrated or other form of rim, so that when the tendencyto side slipping reaches a certain predetermined va ue, the boss isdriven latersiiy against a spring and being simultaneously rotatedcauses the center of rotation of the disk to be lowered and therebybrings the serrated or othr edge of the disk into contact with the roaIn the accompanying drawings, Figure 1 is an elevation and Fig'. 2 is avertical section illustrating an example. of construction of myinvention applied to the wheel of a motor road vehicle fitted for chaintransmission. Figs. 3 and 4 are detail views.

' a is the` ixed axle upon which the hub b of the wheel is free torotate; it is made longer than usual to allow of the hui) also slidingupon the axle to a limited extent. The squared end of the axle carries aconcentric boss c fixed thereto, said boss c carrying an eccentricsheave or boss (l upon which a disk or dummy wheel eis free to rotate.

.In the drawings the disk is shown as being slightly dished and providedwith a rim f; ball bearings may be iitted if desired in any well knownmanner. The eccentric sheave is made to receive a volute web or featheror webs or feathers g fixed to the boss c, (Figs. 3 and 4), analogous toa nut upon a single or multiple screw thread or threads and a spring 11, is provided to o'l'er elastic resistance to the turning and lateralmotions or' the eccentric she we d. In the example shown, the disk e lis held in position by the annular flange plate tric sheave d, and theboss cis provided with an annular iange ring k which may be held inposition by the cup Z, theV latter being screwed into the end of theboss c or otherwise iixed. The eccentric shaft is connected to the wheelin such a manner that the two move laterally as one piece "rwhileermitting either to rotate independently o the other. As shown, this maybe effected by a concentric lange m on the sheave diand an annularflanged plate fn, fixed to the"wheel, ball bearings o or other approvedanti-friction device being preferably provided to reduce friction.

It will be seen that, simultaneously with lateral movement of the wheelupon its axle, the eccentric shaft d is drawn with it and at theSametime partially rotated by the thread g so as to bring the center ofthe dummy wheel nearer the road and cause the disk to come into contactwith the road .and thereby prevent or arrest skidding or side slipping.The lateral motion of the wheel on its ax e or the rotary motion of theeccentric boss may be utilized to liberate or deliver sand from a. sandbox to the road close to the wheel.

I claim:

1. A non-skidding device for wheels 'of vehicles comprising a dummywheel mounted alongside the vehicle wheel, means allowing of lateralmotion of said vehicle wheel upon its axle, a rising and falling bearingcarrying said dummy wheel, and automatic operating and connectin meansbetween said bearing and said vehicle wheel to raise and lower saiddummy wheel.

2. A non-skidding device coniprisin a vehicle wheel mounted to slide aswe as rotate upon its axle, a dummy wheel mounted to rotate alongsidethe vehicle Wheel, a vertically movable bearing carrying said dummywheel, means connecting the said wheels and means raising and depressingsaid dummy wheel.

3. A non-skiddino device comprisino a. vehicle wheel capable of slidingas we as rotating upon its axle, a concentric bos-s fixed on said axle,an eccentric bearinu boss mounted to rotate on said concentriclioss, adummy Wheel mounted to rotate on said bearing boss nieans'connecting thevehicle wheel with the eccentric bearing boss, and means partiallyrotating said hearing boss when said vehicle wheel slides upon its axle,as set forth. f
